The invention provides a real-time control method and system for traction force of a power distributed electric locomotive, and the system comprises a central control unit, a main driving mechanism and a plurality of first slave driving mechanisms which are arranged on a locomotive head, and also comprises muck weight monitoring units and a plurality of second slave driving mechanisms which are arranged on all power muck trucks; each driving mechanism comprises a motor and a corresponding variable frequency driving control unit; based on the operation instruction and the starting instruction, a main motor output torque is obtained by utilizing a central control unit and a variable frequency driving control unit in a main driving mechanism; the central control unit obtains slave motor following torque of the slave driving mechanism based on the output torque of the main motor, the empty load weight of the power muck truck, the muck weight, the full load rated weight of the power muck truck and the motor rated torque of each driving mechanism, and determines the given frequency of the slave motor based on the given frequency after the slope and the inching setting frequency. And then the slave motor following torque and the slave motor given frequency are utilized to control motor operation of the slave driving mechanism.

    本申请提出一种动力分散式电机车牵引力实时控制方法和系统,其中系统包括设置在机车头的中央控制单元、主驱动机构和多个第一从驱动机构,还包括设置在各台动力渣土车的渣土重量监测单元和多个第二从驱动机构;各驱动机构包括电机和对应的变频驱动控制单元;基于运行指令和启动指令,利用中央控制单元和主驱动机构内的变频驱动控制单元得到主电机输出力矩,中央控制单元还基于主电机输出力矩、动力渣土车空载重量、渣土重量、动力渣土车满载额定重量、各驱动机构的电机额定扭矩获得从驱动机构的从电机跟随力矩,还基于斜坡后给定频率和点动设置频率确定从电机给定频率,进而利用从电机跟随力矩和从电机给定频率控制从驱动机构的电机运行。
